when the handle lacks DELETE access
- Avoid unnecessary zeroing of large SMB2 read buffers
- Add an oplock list lockdep annotation and update the documented
support status for durable handles and SMB3.1.1 compression
- Durable handle fixes to address ownership and lifetime races during
reconnect, session teardown, oplock handling, and superseding opens,
preventing stale session and file references from being used by
concurrent operations

Pull VFIO fixes from Alex Williamson:
"Mostly straightforward fixes here, inconsistent runtime PM handling
due to global device policies, bitfield races, unwind path gaps,
teardown ordering, and a misplaced library flag.
- Fix racy bitfield updates in vfio-pci-core and the mlx5 vfio-pci
variant driver with a binary split between setup/release and
runtime modified flags. These were noted across several Sashiko
reviews as pre-existing issues (Alex Williamson)
- Fix runtime PM inconsistency where the vfio-pci driver module_init
could modify the idle PM policy of existing devices through globals
managed in vfio-pci-core, leading to unbalanced runtime PM
operations (Alex Williamson)
- Restore mutability of writable vfio-pci module options by further
pulling policy globals out of vfio-pci-core, to instead be latched
per device at device init. Provide visibility of the per device
latched values through debugfs (Alex Williamson)
- Fix missing VGA arbiter uninit callback in unwind path (Alex
Williamson)
- Reorder device debugfs removal before device_del() to avoid gap
where debugfs is available with stale devres pointers (Alex
Williamson)
- Move UUID library linking flag from vfio selftest Makefile into
libvfio.mk to avoid exposing such dependencies when linking with
KVM selftests (Sean Christopherson)"

This SPI controller likely belongs to a power domain for all the SoCs
listed. For sure, it belongs to one on the Renesas RZ/N1 SoC, so
enable the property to be able to describe its power domain in DTs.

Commit 164c05f03ffa ("spi: Convert DW SPI binding to DT schema") added
an RZ/N1 entry which was not in the original txt-file. It doesn't follow
the usual "<soc entry>, <soc family entry>" style for Renesas SoCs which
was properly added later with commit 029d32a892a8 ("spi: dw-apb-ssi:
Integrate Renesas RZ/N1 SPI controller"). In that commit, removing the
bogus entry was overlooked and is finally done now.

The nointxmask and disable_idle_d3 module parameters remain writable,
but vfio-pci now latches their values into each device at init. Once a
device is registered, changing the module parameter only affects future
devices, leaving no direct way to confirm the effective policy for an
existing device.
Add a pci debugfs directory under the VFIO device debugfs root and
report the per-device nointxmask and disable_idle_d3 values. These are
read-only debugfs views and use the same Y/N bool output convention as
the module parameters.
Read-only vfio-pci parameters, such as disable_vga, are not exposed here
because they cannot drift from the latched device value, therefore the
existing module parameter exposure via sysfs is sufficient.
Note that while only vfio-pci currently provides these options, the
implementation is in vfio-pci-core and therefore properly reflects the
device policy in the core, regardless of driver.

vlan_device_event() generates nested UP/DOWN, MTU and feature
change events. It executes an event for the VLAN device directly
from the notifier - while the locks of the lower device are held.
This causes deadlocks, for example:
bond (3) bond_update_speed_duplex(vlan)
| ^ v
vlan (2) UP(vlan) (4) vlan_ethtool_get_link_ksettings()
| ^ v
dummy (1) UP(dummy) (5) __ethtool_get_link_ksettings()
The dummy device is ops locked, vlan creates a nested event (2),
then bond wants to ask vlan for link state (3). bond uses the
"I'm already holding the instance lock" flavor of API. But in
this case the lock held refers to vlan itself. We hit vlan's
link settings trampoline (4) and call __ethtool_get_link_ksettings()
which tries to lock dummy. Deadlock. There's no clean way for us
to tell the vlan_ethtool_get_link_ksettings() that the caller
is already in lower device's critical section.
Defer the propagation to the per-netdev work facility instead:
the notifier only schedules netdev_work_sched(vlandev, VLAN_WORK_*),
and ndo_work (vlan_dev_work) applies the change later. Hopefully
nobody expects the VLAN state changes to be instantaneous.
If someone does expect the changes to be instantaneous we will
have to do the same thing Stan did for rx_mode and "strategically"
place sync calls, to make sure such delayed works are executed
after we drop the ops lock but before we drop rtnl_lock.
Stan suggests that if we need that down the line we may
consider reshaping the mechanism into "async notifications".
AFAICT only vlan does this sort of netdev open chaining,
so as a first try I think that sticking the complexity into
the vlan code makes sense.
One corner case is that we need to cancel the event if user
explicitly changes the state before work could run. Consider
the following operations with vlan0 on top of dummy0:
ip link set dev dummy0 up # queues work to up vlan0
ip link set dev vlan0 down # user explicitly downs the vlan
ndo_work # acts on the stale event

Emails to the maintainer of Qualcomm PPE Ethernet driver (Luo Jie
<quic_luoj@quicinc.com>) bounce permanently (full mailbox), because the
"quicinc.com" addresses were deprecated for public work. All Qualcomm
contributors are aware of that and were asked to fix their addresses.
Driver is not supported - in terms of how netdev understands supported
commitment - if maintainer does not care to receive the patches for its
code, so demote it to "maintained" to reflect true status.
Fix all occurences of Luo Jie email address to preferred and working

Like other architectures such as x86, arm64, riscv, powerpc and s390,
select THREAD_INFO_IN_TASK for LoongArch to move thread_info off the
stack into task_struct. This follows modern kernel standards and also
makes the system more secure.
With this patch, thread_info is included in task_struct at an offset
of 0 instead of being placed at the bottom of the kernel stack. Thus,
the $tp register points to both thread_info and task_struct.
To support this, introduce a per-CPU variable cpu_tasks to store the
pointer to the current task_struct. This decouples the recovery of the
$tp register from the stack pointer during exception entry.
Then initialize cpu_tasks for the primary and secondary CPUs during
arch-specific setup and SMP boot paths. To eliminate the dangerous
windows during the early initialization where the cpu_tasks remains
uninitialized, set_current() is invoked as early as possible in both
setup_arch() and start_secondary(). This ensures the $tp recovery
barrier is armed in case any early boot exceptions or kernel panics
occur.
Modify SAVE_SOME and handle_syscall to restore the $tp register from
cpu_tasks, and also use the la_abs absolute addressing for cpu_tasks
access in assembly to bypass the relocation limits within exception
handling sections. By advancing the preservation of u0 in SAVE_SOME,
we reuse the PERCPU_BASE_KS value in u0 for the cpu_tasks calculation,
effectively eliminating a duplicate csrrd instruction execution on SMP
platforms.
Update <asm/switch_to.h> and <kernel/switch.S> to fully support the
CONFIG_THREAD_INFO_IN_TASK feature.
Remove the obsolete next_ti argument from __switch_to(), which shifts
the remaining arguments ahead in the calling convention (sched_ra from
a3 to a2, and sched_cfa from a4 to a3). Under the new configuration,
__switch_to() now directly derives the thread pointer ($tp) from the
next task_struct pointer in a1.
To preserve the optimal and clean "move tp, a1" path for 64-bit kernels,
the thread pointer ($tp) is assigned directly from a1 in the core path.
For 32-bit kernels, where a1 carries a 2000-byte structural pointer bias
at entry, an explicit adjustment "PTR_ADDI tp, tp, -TASK_STRUCT_OFFSET"
is introduced at the function exit.
In the context of __switch_to(), local interrupts are disabled, and the
kernel is in a critical switching phase where handling any synchronous
exception is practically impossible and prohibited.
If any synchronous exception or watchpoint does trigger in this narrow
window, it constitutes a fatal double fault and the kernel is expected
to die/panic immediately anyway. Therefore, the temporary biased value
in $tp is safe and acceptable here.
Additionally, evaluate the stack lookup as a single load instruction
"LONG_LPTR t0, a1, (TASK_STACK - TASK_STRUCT_OFFSET)", this perfectly
satisfies both 32-bit and 64-bit kernels. Using the "next" pointer in
a1 as the base register, rather than $tp, effectively unchains the data
dependency (RAW hazard) from the preceding move instruction, maximizing
the instruction-level parallelism and superscalar execution efficiency
while naturally adapting the structural shift.
With CONFIG_THREAD_INFO_IN_TASK enabled, the kernel stack life cycle is
decoupled from task_struct and can be freed concurrently.
Currently, show_stacktrace() reads raw stack data via __get_addr() and
subsequently calls show_backtrace() to unwind the frame, without holding
any reference to the target task's stack. If show_stacktrace() is called
on a concurrently exiting task, it could attempt to read from a freed or
reallocated kernel stack. This introduces a severe use-after-free (UAF)
read risk or kernel panics.
Wrap the entire stack inspection process inside show_stacktrace() with
a try_get_task_stack() and put_task_stack() pair. This ensures the task
stack remains pinned safely during both the raw stack data dump loop and
the subsequent stack unwinding phase.
Also, ensure that the task pointer is initialized to "current" early if
it is NULL, so that try_get_task_stack() always operates on a valid task
reference.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
around a WiFi device defect; use a quirk or boot-time
"pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)
- Always lift 2.5GT/s restriction in PCIe failed link retraining to
avoid clamping a link to 2.5GT/s after hot-plug changes the device
(Maciej W. Rozycki)
- Request bus reassignment when not probe-only to fix an enumeration
regression on Marvell CN106XX and possibly other DT-based systems
(Ratheesh Kannoth)
- Fix procfs race between pci_proc_init() and pci_bus_add_device()
that resulted in 'proc_dir_entry ... already registered' warnings
and pointer corruption (Krzysztof Wilczyński)
- Fix sysfs race that causes 'duplicate filename' warnings and boot
panics by converting PCI resource files to static attributes
(Krzysztof Wilczyński)
- Expose sysfs 'resourceN_resize' attributes only on platforms with
PCI mmap (Krzysztof Wilczyński)
- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
attributes (Krzysztof Wilczyński)
- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
mmap path to match the generic path (Krzysztof Wilczyński)
- Use kstrtobool() to parse the 'rom' attribute input to avoid the
unexpected behavior of enabling the ROM when writing '0' with no
trailing newline (Krzysztof Wilczyński)
Resource management:
- Improve resource claim logging for debuggability (Ilpo Järvinen)
- Clean up several uses of const parameters (Ilpo Järvinen)
- Check option ROM header signatures and lengths before accessing to
avoid page faults and alignment faults (Guixin Liu)
ASPM:
- Don't reconfigure ASPM when entering low-power D-state; only do it
when returning back to D0 (Carlos Bilbao)
Power management:
- During suspend, set power state to 'unknown' for all devices, not
just those with drivers (Lukas Wunner)
- Skip restoring Resizable BARs and VF Resizable BARs if device
doesn't respond to config reads, to avoid invalid array accesses
(Marco Nenciarini)
- Add pci_suspend_retains_context() so drivers can tell whether
devices retain internal state across suspend/resume, since some
platforms reset devices on suspend; use this in nvme to avoid
issues on Qcom RCs (Manivannan Sadhasivam)
Power control:
- Only to power on/off devices that actually support power control to
avoid poking at incompatible devices mentioned in DT (Manivannan
Sadhasivam)
Virtualization and resets:
- Log device readiness timeouts as errors, not warnings, because the
device is likely unusable in this case (Bjorn Helgaas)
- Wait for device readiness after soft reset (D3hot ->
D0uninitialized transition), when the device may respond with
Request Retry Status (RRS) if it needs more time to initialize
(Bjorn Helgaas)
- Drop unnecessary retries when restoring BARs because resets should
now already include all required delays (Lukas Wunner)
- Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
terminates uncleanly (Jose Ignacio Tornos Martinez)
- Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
which seem not to support it correctly (Jose Ignacio Tornos
Martinez)

fails (Koichiro Den)
- Validate BAR index and remove dead BAR read in endpoint doorbell
test (Carlos Bilbao)
- Unwind MSI/MSI-X vectors if NTB initialization fails part-way
through (Koichiro Den)
- Cache sleepable pci_irq_vector() value at ISR setup to avoid
calling it from hardirq context (Koichiro Den)
- Call sleepable pci_epc_raise_irq() from a work item instead of
atomic context, e.g., when setting bits in NTB peer doorbells in
the ntb_peer_db_set() path (Koichiro Den)
- Report 0-based vNTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Prevent configfs writes to vNTB db_count and other values that are
already in use after EPC attach (Koichiro Den)
- Account for vNTB db_valid reserved slots (link event 0 and
historically skipped slot 1) so they don't appear as valid
doorbells (Koichiro Den)

cadence, dwc, iproc, mediatek, plda, rockchip to prevent
use-after-free or crashes when racing with sysfs rescan or hotplug
(Hans Zhang)
- Add pci_host_common_parse_ports() for use by any native driver to

Since commit 2abdc3dcf978 ("dt-bindings: clock: renesas,cpg-clocks:
Document ZT/ZTR trace clock on R-Mobile APE6"), the APE6 clock node
expects two additional "clock-output-names" entries, "zt" and "ztr".
Update the example accordingly.

Pull f2fs updates from Jaegeuk Kim:
"The changes primarily focus on filesystem error reporting, reducing
memory footprint by reverting in-memory data structures used for
runtime validation, honoring FDP hints, and adding trace and debug
logs. In addition, there are critical bug fixes resolving
out-of-bounds read vulnerabilities in inline directory and ACL
handling, potential deadlocks in balance_fs, use-after-free issues in
atomic writes, and false data/node type assignments in large sections.
Enhancements:
- Revert in-memory sit version and block bitmaps
- support to report fserror
- add trace_f2fs_fault_report
- add iostat latency tracking for direct IO
- add logs in f2fs_disable_checkpoint()
- honor per-I/O write streams for direct writes
- map data writes to FDP streams
- skip inode folio lookup for cached overwrite
- skip direct I/O iostat context when disabled
- revert "check in-memory block bitmap"
- revert "check in-memory sit version bitmap"
Fixes:
- optimize representative type determination in GC
- fix incorrect FI_NO_EXTENT handling in __destroy_extent_node()
- fix potential deadlock in f2fs_balance_fs()
- fix potential deadlock in gc_merge path of f2fs_balance_fs()
- atomic: fix UAF issue on f2fs_inode_info.atomic_inode
- fix missing read bio submission on large folio error
- pass correct iostat type for single node writes
- fix to do sanity check on f2fs_get_node_folio_ra()
- validate orphan inode entry count
- keep atomic write retry from zeroing original data
- read COW data with the original inode during atomic write
- validate inline dentry name lengths before conversion
- validate dentry name length before lookup compares it
- reject setattr size changes on large folio files
- revert "remove non-uptodate folio from the page cache in move_data_block"
- validate ACL entry sizes in f2fs_acl_from_disk()
- bound i_inline_xattr_size for non-inline-xattr inodes
- fix listxattr handling of corrupted xattr entries
- fix to round down start offset of fallocate for pin file"
